The yellow flame of a Bunsen burner consists of three distinct regions: the inner cone, the outer cone, and the luminous zone. The inner cone is the hottest part, where complete combustion occurs, producing a blue flame. The outer cone surrounds the inner cone and indicates incomplete combustion, resulting in a cooler temperature and the yellow coloration. The luminous zone is the area where unburned carbon particles are present, giving the flame its yellow appearance due to incandescence.
